At Nicholas' home, he is standing before his mirror, all dressed up in his red suit. He wanted to make sure everything about his appearance was perfect.

"I do have to thank Papa Smurf for giving me the idea of dressing up like this," Nicholas said as he saw himself in the mirror. "It truly gives me a rather festive appearance that has served me well over the years. Of course, I do have to wonder if I would be able to find a successor to my line of work or not, but at least nobody can be frightened by my appearance tonight."

Soon he could hear the sound of carolers outside his door, traveling through the forest to share their glad tidings with whoever they would come across. He always enjoyed listening to people singing the praises of the holidays, even if the praises were to a God that he was completely unfamiliar with.

"Yes, well, time to get myself ready to fly," Nicholas said as he grabbed his bag and his list of good and bad children before leaving the house. Outside the stars were glistening in the night sky, which he took for a good omen.

He went to his stables and loosed the reindeer so that he could get them harnessed for pulling the sleigh. "All right, my friends, you know by heart how we're going to proceed tonight," he said to the reindeer as he harnessed them together. "We'll land quietly outside the houses and you'll wait long enough for me to deliver the presents. Nobody is to ever know that we'll be there inside each family's house, especially the children, though if they do, the parents will think that the children are just seeing things."

One of the reindeer poked at Nicholas, as if to remind him of something. "Oh, yes, my special sugar cubes for each and every one of you," Nicholas said as he went back into the house to get them. "Papa Smurf said that these special cubes will be enough to make each one of you fly." He fed each of the eight reindeer a sugar cube, which they quickly ingested.

"There," Nicholas said after the last reindeer was fed a sugar cube. "Pretty soon we're going to get ourselves underway for our yearly mission."

In Chlorhydris' castle, her laboratory is full of thick icy smoke emanating from her cauldron. It is so chilly that it's making everything in her laboratory freeze up.

"There, the Split Pea Soup Fog formula is ready at last!" the evil witch said, pleased with the results. She ladled some of it into a bowl. "Now all I have to do is cast it out into the clear black sky, and soon the vapors of the formula will rise and cause thick dark clouds to form that will blanket the entire region and make it impossible for anyone to see what's right in front of their faces. And then the festive spirit of Christmas will grow cold and dark, and Nicholas will not able to deliver his gifts to the children tonight. Oh, how delightful it will be when they wake on Christmas morning only to discover that there are no toys left for them, and their little hearts will break and they will see for themselves how petty and cruel the world can be."

She went outside of the observatory and lifted the bowl containing the formula into the air. "Rise, rise, into the skies, give this holiday an unwelcome surprise!" she said, laughing.

And soon the vapors of the formula rose high into the air and formed thick clouds that filled the sky and descended down to the ground, covering the whole region in a thick fog that made it impossible for anyone to see beyond what was in front of their faces.

In the Smurf Village, the dense fog was so thick that the Smurfs ended up bumping into each other and into their houses as they went about. Except for Empath, who was able to navigate through the fog only by using his minds-eye, it was impossible for any Smurf to go in any direction anywhere.

"This fog is so unnaturally thick, my little Smurfs, I smurf that there's an evil magic behind this," Papa Smurf said. "Until I can find a way to smurf away much of the fog so that we'd at least be able to smurf around the village, it would be best for all of us to smurf inside our own homes tonight."

"That's true, Smurfette," Papa Smurf said. "But even more so, Nicholas won't be able to smurf through the sky with his sleigh like he normally smurfs around this time. If he isn't able to smurf his presents to the children by around midnight, they will wake up on Christmas morning and be heartbroken."

"There's got to be something we can smurf for him, Papa Smurf, but I'm all out of bright ideas," Brainy said.

Just then a brilliant red light shone through the fog, causing it to disperse around Brainy. Everyone noticed that the brilliant red light came from the reindeer's red nose.

"That's it!" Empath realized. "The reindeer with the red nose can help Nicholas lead his team of reindeer safely through the sky. Brainy, you just came up with a bright idea!"

"I did? Oh, yes, well, I knew something like this had to smurf up sooner or later!" Brainy said, sounding sure of himself.

Empath turned to the reindeer. "This smurf will take us into the sky and guide us to Nicholas' home while you clear the sky with your red nose. This smurf will find you a home yet."

The reindeer nodded as he allowed Empath to ride on his back. The Smurfs watched as Empath and the reindeer flew into the sky, with the reindeer's red nose shining like a beacon through the thick fog.

At Nicholas' home, the toymaker was ready to make his toy deliveries with his team of reindeer when he noticed the thick fog covering the entire region.

"Of all the things to happen on a Christmas Eve!" Nicholas said, sounding frustrated. "Well, don't worry, my reindeer friends, we will find some way to get the presents delivered on time for all the children...if there is some way we can travel through this fog!"

Just then he saw a red glow flying through the sky, coming down towards him. He saw that it was reindeer with a glowing red nose, and riding him was a Smurf.

"My fellow Smurf, what is this that you bring to my home tonight?" Nicholas asked, wondering about the reindeer.

"Fellow Nicholas, this is a reindeer that the Smurfs have found in our forest today," Empath explained. "He has been living alone in the forest because of his red nose, which you can see is able to shine brightly enough so that you will be able to travel through the skies to make your deliveries. We humbly offer him to you in the hopes that he will help you and that you will give him a suitable home. Will you accept?"

Nicholas didn't know what to say. "By Jove, this is such an excellent gift! Surely he will able to help me, and I will surely make sure that he has a home so that he will not be alone anymore. I must put him at the head of my reindeer team by making some adjustments. I will name him Rudolph, which is the name of the brightest child in the village."

The reindeer licked Nicholas' face, happy in that the toymaker has accepted him. Soon with a few adjustments and a sugar cube, Rudolph was put at the head of the team of reindeer, with Nicholas ready to ride off into the night sky.

"I must pay homage to Mother Nature for this wonderful gift that was bestowed upon me, fellow Smurf," Nicholas said, happy and eager to get his flight started. "Thank you again for bringing Rudolph to me!"

"And thank you for giving him a home, Nicholas," Empath said in return. "May you have a Merry Christmas!"

"And the same to you, my friend!" Nicholas said as Empath flew off. Then he turned to his reindeer team. "All ready, Rudolph! Lead the way!"

And so with Rudolph's red nose shining bright, Nicholas and sleigh lifted off into the night sky, on his way to delivering the toys and presents to the children.

Back in the Smurf Village, Papa Smurf had finished working on a formula that caused the fog to disperse around the area of the Smurf Village. The Smurfs cheered as they are able to now walk around the village with no problem.

Soon Empath had returned, and was dressed up in his reindeer costume, but every Smurf noticed that Empath had worn red paint on his nose. "Hey, Empath, what's with the red nose?" Jokey asked, laughing. "You're going to smurf like that reindeer now?"

"That's what this smurf is going to do, Jokey," Empath answered, smiling but not laughing. "Nicholas is now delivering his presents to the children thanks to the reindeer he now calls Rudolph. And this smurf is going to be the lead of the reindeer team."

"Does that mean I get to be part of the reindeer team now, Empath?" Nat asked. "I already have the costume for it."

Empath smiled. "This smurf doesn't see why not, Nat. But with the harnesses only able to hold eight reindeer, this smurf will have to hold onto those of the first two reindeer while we make our flight."

"Hold on, Empath," Tanner said as he wrapped some rope around Empath's waist and attached it to the harnesses. "There, that should smurf it!"

"Okay, all of my reindeer Smurfs, time to smurf into costume!" Papa Smurf said.

And soon Papa Smurf and the nine Smurfs who are part of the reindeer team are ready to make their first flight over the forest. "Okay, Empath, steady as it smurfs!"

Empath nodded as he used his minds-eye abilities to lift up both the sleigh and the reindeer team into the night sky. The Smurfs down below the village cheered and waved goodbye as they watched the sleigh take off.

Then Smurfette led the Smurfs into singing Christmas carols: "Smurf, the herald angels sing, glory to the newborn King,..."

The following day, on Christmas morning, Empath went off to Nicholas' home to pay Rudolph a visit. The skies were still cloudy, but the thick fog was dispersing at ground level. There Empath saw that Rudolph was happy in his new home -- and much more than that!

"Great Ancestors!" Empath exclaimed as he saw another reindeer, a female, approach the fence and nuzzle alongside Rudolph. "It appears that you now have a mate! This smurf is happy that you won't be alone anymore!"

Just then, Mother Nature appeared from out of nowhere. "Oh my...so this is where the poor reindeer I have given the red nose to has gone off to," she said, sounding regretful. "All those years, and I have not fixed this mistake because there was just so much for me to do. Well, not any longer. It is time to give this reindeer the normal life that he deserves."

"Please, Mother Nature, don't change him," Empath pleaded. "If it weren't for this mistake of yours, this Christmas would have been a terrible one for the human children. Look at how happy he is now knowing what he has done and who now loves him. Take that away from him and he won't be the same anymore. He won't be as useful as he is with the red nose."

Mother Nature pondered what Empath had told her. "Come to think of it, some of my mistakes have provided benefits that I would never have foreseen even with my power," she said. "Very well, if he is happy with the way he is now, I shall leave him be and deal with this dreadful fog that's been covering my forest. Have a merry Christmas, little Smurf, and see you in the spring!"

With that, Mother Nature disappeared in a sprinkle of snowflakes. Empath realized it is time to go home and open his presents, particularly the one that Smurfette had made for him.

"Farewell, my reindeer friends, and have a merry Christmas," Empath said as he flew off, watching the reindeer couple nuzzle each other, happy to be together.

Later in the village, as the Smurfs were enjoying their Christmas feast together, the Smurflings got everyone's attention for something important.

"We've just smurfed up with a special song to celebrate our new reindeer friend being part of Mr. Nicholas' sleigh team," Snappy announced.

And without any further introduction, the Smurflings began to sing:

Rudolph the red-nosed reindeer
Had a very shiny nose
And if you ever smurfed it,
You would even say it glows
All of the other reindeer
Used to laugh and smurf him names
They never let poor Rudolph
Join in any reindeer games
Then one foggy Christmas Eve,
Santa came to say:
"Rudolph, with your nose so bright,
Won't you smurf my sleigh tonight?"
Then how the reindeer loved him
As they shouted out with glee,
"Rudolph the red-nosed reindeer,
You'll smurf down in history"

Every Smurf clapped at the end of the performance of the song. "That was the smurfiest song I have ever heard composed besides 'Smurfbop'," Harmony said.

"I hate 'Smurfbop'," Grouchy said.

"So what do you think of the song, Empath?" Nat asked.

"This smurf believes that Rudolph will be pleased to know how he will be remembered as the reindeer that saved Christmas through your musical composition, Nat," Empath said.

"I'm just glad that we managed to save that poor reindeer out in the forest and that he's much happier where he is now, Empath," Smurfette said.

"Just seeing Rudolph with his mate on the morning after makes this smurf wish for a similar Christmas present to come this way, Smurfette," Empath said.

"You don't have to wait for that present, Empath," Smurfette said as she looked into his eyes.

"It's just that this smurf isn't ready to unwrap that present yet, Smurfette," Empath said as he looked into hers.

"Oh, you silly, Empath...I meant that you have the best present of friendship smurfing right here beside you," Smurfette said.

"Well, at least that present is one this smurf can enjoy all year round," Empath said as he and Smurfette both kissed each other.

And at that point, Rapper got up from his seat and decided to join the Smurflings in a repeat performance of their new song about Rudolph.
